A New Technique for Computed-Tomography Urethrography in Males: The Clamp Method

The aim of the present study is to describe and evaluate a new technique for performing Computed-Tomography Retrograde Urethrography (CT-RUG). Males with urethral anomalies detected by retrograde urethrography (RUG) and/or sonourethrography (RSUG) underwent CT-RUG using clamp method three radiologists evaluated in each separately blindly. was done successfully all cases (n = 22), means 6 min duration 95 mL contrast; no pain reported 81% patients (VAS: 0) very mild rest 0.5–1.2). showed better diagnostic efficacy periurethral fistula 8), stent 3), previous urethroplasty lithiasis 2), similar accuracy RSUG measuring length anterior strictures 9) greater than RUG (p 0.008). Six received 2 CT sweeps, an effective dose 4.96 mSv, remaining 16 had 1 sweep 3.456 mSv. To best our knowledge, this first CT-RUG, that comfortable both patient operator (retrograde infusion contrast).
